Exodus 29:24-37

You shall put all these on the palms of Aaron and on the palms of his sons, and wave them for a wave offering before the LORD. Then you shall take them from their hands and burn them on the altar on top of the burnt offering, as a pleasing aroma before the LORD. It is a food offering to the LORD. “You shall take the breast of the ram of Aaron’s ordination and wave it for a wave offering before the LORD, and it shall be your portion. And you shall consecrate the breast of the wave offering that is waved and the thigh of the priests’ portion that is contributed from the ram of ordination, from what was Aaron’s and his sons’. It shall be for Aaron and his sons as a perpetual due from the people of Israel, for it is a contribution. It shall be a contribution from the people of Israel from their peace offerings, their contribution to the LORD. “The holy garments of Aaron shall be for his sons after him; they shall be anointed in them and ordained in them. The son who succeeds him as priest, who comes into the tent of meeting to minister in the Holy Place, shall wear them seven days. “You shall take the ram of ordination and boil its flesh in a holy place. And Aaron and his sons shall eat the flesh of the ram and the bread that is in the basket in the entrance of the tent of meeting. They shall eat those things with which atonement was made at their ordination and consecration, but an outsider shall not eat of them, because they are holy. And if any of the flesh for the ordination or of the bread remain until the morning, then you shall burn the remainder with fire. It shall not be eaten, because it is holy. “Thus you shall do to Aaron and to his sons, according to all that I have commanded you. Through seven days shall you ordain them, and every day you shall offer a bull as a sin offering for atonement. Also you shall purify the altar, when you make atonement for it, and shall anoint it to consecrate it. Seven days you shall make atonement for the altar and consecrate it, and the altar shall be most holy. Whatever touches the altar shall become holy.
